I haven't revisited the OP yet, but I can't beat Beowulf on hard!
I can't do it with Royalguard at level 1. So I think I will stick with either swordmaster or trickster, but it's so hard to evade his attacks! And I do not know how to evade his projectiles
I always just use E&I to hover above his punches and helm breaker on him. Do you mean the cages or the attack where he shoots a ton of shit out? When he shoots a lot just run behind him.
I do struggle with him without RG though. And I forgot how bad I am without level 2 for air guard, I guess I relied on that more than I realized.
